Evolve

Evolve is a world of player initiative. If the players want adventure its up to them to seek it out.

from the time there character first sets foot in the world of Evolve to their characters death or personification as a deity they live the life there character normally would.

Every action they choose to take (or not to) changes the world to some degree. Helping the bandits might cause a village to die of starvation. While protecting a village might cause it to become a political power house. however not all actions the players take will be so influential, but they have the potential to be so.
